Abstract : The report documents the Curve Fitting and First Quadrant Plotting Program (CURVPLOT) which was developed primarily to present graphically the effectiveness and cost effectiveness data for various weapons systems. The finished program products (plots) show the relative merits of two weapons systems. The program can also be used to plot any relatively smooth set of three or more X,Y points that satisfy the program restrictions. The program was designed to be used on the Wang 720B Electronic Programmable Calculator and 702 Plotting Output Writer combination. The regular plotter typing element is replaced with an IBM Dual Gothic typing element. (Author)
